On acreage, so nobody can see it.
H says "thank God".
Both Washingtonia filifera have C-9 Christmas lights around the base on a thermocube, piled bags of leaves, 4" fibreglass insulation near the top:

Hope this is enough air space inside:

Plastic over it all, tied:

The 3 Yucca rostrata in between the Washies have C-9s at the base on the same thermocube as Washies.

Looks like a dog's breakfast...but I'm finally ready for winter.

I just hope the bagged leaves don't collapse onto the palms as they settle/freeze/thaw.

OK, winter, bring it on

And H is thrilled that I raked leaves...
